So the plot thickens, I have looked at my 2005-2012 RRS DTCs.
I cant find a U0102 .

But all I can say is, if the car drove then broke down and was taken to a garage where some work was done I would investigate electrical connections as a first port of call.

And of course we all wait for Phil to come back with the answer :).

Definitely thickens lol

It’s such a strange fault especially the fact it shows it’s going into RND etc and the cable moves and you can hear it move in the gearbox yet the car doesn’t

Who/what gave you the codes?
As I said it may shift but as it doesn't know all is well it says "nope"

If you put the gearbox in neutral with the handbrake off can you move it?

Is there any oil in the gearbox?

Hi mark , there is , but I’m now thinking maybe too much. I had the car raised at the side so the fill plug was higher and when I started to undo the plug it started ****ing out. Would too much oil in gearbox cause the lack of movement when I gear?

There is a correct filling procedure which includes final filling at the right temperature. With the engine not running, oil will pour out. I doubt it's overfilled and I doubt that even if it is it would stop the car moving, might cause problems in use though.
Gear selection is done electronically, so corroded connectors are a possibility.

I will check connectors again just incase. Would it just be the multiplug that goes into the gearbox?
 
Undone the fill plug for gearbox oil when car was flat and it was a small trickle , from what I can see that’s correct ?

That one, but because of the CAN BUS system, there could be faults in other connectors or modules that would stop the gearbox from working. Not really an area I know a lot about.

There maybe(probably) 1 to the transfer box too.
As the fault seems to show coms between the 2.

I think there is 2 to the rear of the gearbox. I’ll be back at it tomorrow. I’ve noticed there is a comms fault with the parking assist module so I will locate that tomorrow and see just incase that’s throwing everything off

Thars a good call as a lot of systems are linked and a code from one module can come from somewhere else sometimes 🤔

I’m hoping and praying it’s something silly. Would I be correct in saying the parking assist module is in the boot behind side carpet?
